The wii u needs its exclusives also, not only can the 3ds/new 3ds not be able to run it, its not meant for 3ds anyways. Not only will it feel weird, the screen will be way too small to create levels. Nintendo is trying to carry the message that you should get a wii u if you want to play this game, its how it works, it much better as a wii u exclusive anyways. Do not think that evrey game that comes to the wii u will come to the 3ds, systems need their exclusives and the 3ds can't run Mario maker, it will be terrible. The 3ds has its exclusives and they never came to the wii u and its the same for the wii u, the wii u has its exclusives which will not come on the 3ds
